Application February 13, 1939, Serial No. 256,127

2 Claims.

My invention relates to sorting devices and especially to the attachingmeans for the units, where a series of superimposed swinging separatingtabs are attached to blocks engaging a base member or tray such as isshown, for instance, in the patent granted to me March 27, 1934, Number1,952,118.

It has for an object a flexible connection that is simple, strong andeasily constructed of conventional parts.

A further object of my invention is to provide a readily attachable anddetachable tab for use 7 in sorting devices where a large number of tabsare detachably placed in a tray and a series of such trays are placed ina machine such as shown in my Patent No. 1,952,117, dated March 27,1934, said tab having a very thin base and being of light weight.

In the accompanying drawing:

Fig. 1 is a view of a tab I with the attaching means embodying myinvention;

Fig. 2 is a, view similar to Fig. 1 showing a modification;

Fig. 3 is a view similar to Fig. 1 showing the application of myinvention to a bifurcated tab;

Fig. 4 is a section on the line 4-4, Fig. 1;

Fig. 5 is a section on the line 5-5, Fig. 2, and

Fig. 6 is a section on the line 6-6, Fig. 3.

I is the tab proper and 2, Fig. 1, is the wooden block having notches inits ends adapted to engage the inturned edges of the base or tray 3. 4indicates staples having horizontal cross-pieces 5-5 at their tops andparallel prongs extending vertically through the blocks 2 and clenchedtoward each other at their lower ends. Suitably located slots 6-6 areformed through the tab I, adjacent, parallel to and spaced from itslower edge. 'I-I indicate sheet metal strips passing around thecross-pieces intermediate the ends of said cross-pieces and shapedclosely to said crosspieces so as to form cylindrical bearings therefor.

They the-n extend upward in parallel and contiguous portions, saidportions passing along opposite surfaces of the tab I, one of saidportions passing through a slot then downward along the surface of thetab I, then bending outward and downward over the end of the otherportion of said strip.

In the construction of Figs. 2 and 5, there are two blocks 2 which maybe enclosed between thin strips 2a of suitable material, preferably woodfor lightness, and the whole secured together by horizontal staples 8.

In Fig. 3 the tab is shown as being similar to that of 2 but dividedinto two branches at its lower end and a half block 2b with its engagingnotch at its outer end is secured to each branch. This enables thebranches to be bent inward as indicated in broken lines to free the tabfrom the base. Three blocks 21) secured as in Fig. 5 are indicated inFig. 6, with tabs secured to them as above described.

I claim:

1. A tab for use in sorting machines comprising a card having abifurcated lower portion, a thin two part block for said card made oflight material, a thin hinge construction pivotally connecting eachportion of the bifurcated card with one part of the block and means onthe outer end of each block part for ready attachment to and detachmentfrom a tray in which the tab blocks are adapted to be engaged.

2. A tab for use in sorting machines comprising, a card having abifurcated lower portion, a thin two part block of a light material, athin hinge construction pivotally connecting each portion of thebifurcated card with one part of the block, and notches in the outerends of the two parts of the block for receiving the inturned edges of atray in which the tab blocks are to be mounted.
